hmm I think it would be nicer to handle at least the 
CannotActivateFactoryException problems from the filter instatiations 
and pop a dialog ( debug output to terminal especially on weirdy windows 
is not the best way to see this problem ), I vaguely recall the twisted 
mechanism for getting some dialogs to pop with the interaction handler 
stuff, I will have a look

don't see one, don't see that it is so bad either
